Likely causes
Insufficient light
Most likelyHow to tell: The grass looks thin and stretched, and it fails to produce seed heads in the spring. It is likely growing in partial shade.
What to do: Move the plant or prune back surrounding trees to ensure it receives full, direct sun. This grass requires at least 6 to 8 hours of sun daily to bloom.
Young plant age
PossibleHow to tell: The plant looks healthy and green but is very small. It simply has not reached the maturity needed to produce flowers.
